A. Sophie Blee-Goldman commented on KAFKA-8613: ----------------------------------------------- Just replied on the KIP thread -- will go ahead and assign this ticket to you. It should be pretty straightforward but let me know if you have any questions on the implementation > Set default grace period to 0 > ----------------------------- > > Key: KAFKA-8613 > URL: https://issues.apache.org/jira/browse/KAFKA-8613 > Project: Kafka > Issue Type: Improvement > Components: streams > Reporter: Bruno Cadonna > Assignee: A. Sophie Blee-Goldman > Priority: Blocker > Fix For: 3.0.0 > > > Currently, the grace period is set to retention time if the grace period is > not specified explicitly. The reason for setting the default grace period to > retention time was backward compatibility. Topologies that were implemented > before the introduction of the grace period, added late arriving records to a > window as long as the window existed, i.e., as long as its retention time was > not elapsed. > This unintuitive default grace period has already caused confusion among > users. > For the next major release, we should set the default grace period to > {{Duration.ZERO}}. -- This message was sent by Atlassian Jira (v8.3.4#803005)
